How much HP does a GS300 make?

The Lexus GS300 is a midsize luxury sedan that was produced from 1993 to 2005. The GS300 model typically generates around 220 horsepower (HP) from its 3.0-liter inline six-cylinder engine.


Detailed Breakdown of the GS300's Engine Specifications


The Lexus GS300 was powered by a 3.0-liter 2JZ-GE inline six-cylinder engine. This engine was known for its reliability and smooth power delivery. The specific horsepower output of the GS300's engine varied slightly across the different model years:



  • 1993-1997 GS300 models: 220 HP

  • 1998-2005 GS300 models: 225 HP


The engine was paired with either a 4-speed automatic or 5-speed manual transmission, depending on the model year and market. The GS300 was known for its balanced handling and performance, making it a popular choice among luxury sedan buyers.


Comparison to Other Lexus Models


It's worth noting that the horsepower output of the GS300 was lower than some other Lexus models of the same era. For example, the Lexus IS300 sports sedan, which shared the same 3.0-liter engine, produced 215 HP. The larger Lexus GS400 and GS430 models, with their V8 engines, generated significantly more power, ranging from 290 HP to 300 HP.


However, the GS300's 220-225 HP was still considered respectable performance for a midsize luxury sedan at the time. The car's smooth and refined driving dynamics, along with its Lexus-level build quality, made it a popular choice among buyers seeking a balance of luxury, comfort, and moderate performance.
